    • A method is provided for assigning, to each of a plurality of images within different collections in a group of images selected by a search engine, a position within an order in which the images are to be displayed for viewing. The method comprises assigning an initial handicap value to each collection of images in the group, each collection comprising at least one image of a common origin; calculating a combined ranking score for each image in the group by combining the handicap value of the collection containing the image and a ranking value for the image; selecting, for display in the first position in the order, an image having an optimum combined ranking score relative to the combined ranking scores of the other images in the group; after such image selection step, adjusting the handicap value assigned to the collection from which the selected image has been taken so as to adjust the combined ranking score for each of the remaining images in said collection; and, after such handicap value adjustment step, selecting, for display in the next available position in the order, an image having an optimum combined ranking score relative to the combined ranking scores of the other images remaining in the group. This avoids too many similar looking images being presented in a set of search results and has the effect of spacing out images of the same supplier. This is of benefit to both customers and suppliers in that (i) customers can see images from a wide range of sources whilst any single supplier is prevented from dominating the results, and (ii) suppliers of reasonably equal ranking get a fair chance of having their images displayed in the results.
    • 提供了一种方法,用于将由搜索引擎选择的一组图像中的不同集合内的多个图像中的每一个分配给要显示图像以供观看的顺序内的位置。 该方法包括:向组中的每个图像集合分配初始残差值,每个集合包括至少一个共同起源的图像; 通过组合包含图像的集合的残差值和图像的排序值来计算组中每个图像的组合排名分数; 选择用于以所述顺序显示在所述第一位置的图像,其具有相对于所述组中的其他图像的组合排名得分的最佳组合排名分数; 在这样的图像选择步骤之后,调整分配给所选择的图像的集合的差点值,以调整所述集合中的每个剩余图像的组合排名得分; 并且在所述障碍值调整步骤之后,选择用于在所述次序中的下一可用位置显示具有相对于所述组中剩余的其它图像的组合排名得分的最佳组合排名得分的图像。 这避免了在一组搜索结果中呈现太多相似的图像,并且具有间隔出相同供应商的图像的效果。 这对客户和供应商都是有利的,因为(i)客户可以看到来自广泛来源的图像,而任何一个供应商都不能主导结果,以及(ii)合理平等排名的供应商有机会获得 他们的图像显示在结果中。
